In this case I set up a TR for them and told them to place something everywhere they could and then bounce test it to at least get an idea of what works. A 5.10 gym climber equals about 5.5 outdoors until they get some experience but no one tells them that. Don't get me wrong though, I think the gyms have also done a lot for the sport.
No offense to anyone but it seems that the big thing that gyms do is get people stoked on climbing then set them up to be hurt outdoors. If I meet someone who wants to start climbing I tell them to get a few private days with an AMGA or PCGI certified guide, see if they like it, practice placing pro with the guide and then go to the gym
